Adam Rotter: It will be tight, if the Rangers keep Richards, but the team doesn’t need to add that much and what they do add will come from trades and not the shallow free agent market. Defensive depth, especially with questions about Marc Staal, needs to be addressed, with Steve Eminger likely returning as the seventh defenseman. Up front, the Rangers will have Mats Zuccarello and Derek Dorsett for a full season and likely Chris Kreider with JT Miller kicking around.
